Large-diameter quartz tubes are made of high-purity quartz material, with diameters reaching tens of centimeters and a maximum diameter of one meter. They possess characteristics such as high temperature resistance, corrosion resistance, and excellent light transmittance, making them suitable for large high-temperature furnaces. They are used in large-scale production in fields such as photovoltaics, semiconductors, and metallurgy, oversized fused quartz tube for high temperature applications and are key components of large-scale heat treatment equipment.
